Hi Scott. Hi Roland,

It seems to be JAIN is under a Commercial license. So it leaves me to the only other available option of implementation of SIP protocol by myself. So I'm planing to implement this under the EPL.

Although I have no problem with this as a proposal (SIP protocol implementation under EPL)...and am enthusiastic...it is a very ambitious idea for a GSOC project...as complete SIP implementations will require a significant amount of work. You may want to restrict the scope somewhat for your GSOC project...just to make it realistic for a ~4 month project.


My $0.02. I would also suggest getting Roland's (and helpfully Moritz') input on this as well...if possible.

    Hi Scott, Hi Roland,

    Thanks for the quick response. This is really going to be a very
    exiting project as Scott pointed out :).

    Currently I'm looking at 2 exiting implementations for SIP
    implementations, JAIN SIP from Sun and Mj SIP. MjSIp is under GNU
    GPL. so I'm not going to use it as it is might create issues with
    Eclipse Foundation licensing. But what about JAIN SIP? I'm
    comfortable with implementing the SIP protocol by myself. If you
    think that my implemetation under Eclipse license would best way,
    i can proceed with it. So please let me know about your opinion on
    this.

    Roland, Yeah sure. that's a good point.  Let's have a chat about
    this more before we get in to a path which end up with nothing.
    Here are My contacts.

        Hi Scott, Hi Harshana,

        I would like to pick up on the points made by Scott and
        propose we have a
        chat with respect to your plans (especially with regards to
        media transport)
        so we do not set out on a path that might lead to a dead end.

        Could we have a chat over the next days? Skype(pedros09),
        MSN(pedros09@xxxxxxxxxxx <mailto:pedros09@xxxxxxxxxxx>), phone
        number (+49 176 20070189).

        Regards,
        Roland.

        Betreff: Re: [ecf-dev] SIp Voip implementation

        Hi Harshana,

        Thanks for your proposal and interest.  I think this would be
        a *very*
        exciting project.  We already have a Skype implementation of
        the ECF
        Call API, and would very much like a SIP implementation as
        well (there
        is this bug/enhancement request for this here
        https://bugs.eclipse.org/bugs/show_bug.cgi?id=193388).

        If possible, I would like to engage ECF committer Roland Fru
        in this
        work, as his expertise is in VOIP, SIP, etc.  Also, I would
        like to a
        previous GSOC student Moritz Post, who implemented the ECF
        call API
        using Jingle/Smack API:
        http://wiki.eclipse.org/VoIP_via_the_ECF_Call_API_and_the_Jingle_Protocol

        Both would be great people to have involved with/mentoring your
        project.  I've cc'd this email to both Moritz and
        Roland...Moritz and
        Roland please respond on the ecf-dev mailing list about your
        interest
        and availability for mentoring Harshana's proposal.  Ideally,
        I think it
        would be good to have both Roland and Moritz as mentors for
        this project
        so the duties can be shared and the experience of both of them
        would be
        useful.

        Thanks to all involved.  I think this can/will be very cool.

        Harshana...one question...do you expect to implement the SIP
        protocol
        (i.e. in java) yourself, or are you thinking/planning on using
        some
        existing implementation?  If you are already looking at existing
        implementations...then which ones?  The reason I ask is the
        issues of
        licensing/license compatibility that may/could arise with Eclipse
        Foundation.

        Thanks,

        Scott
